Argon Adsorbed on Titanium Dioxide Rutile

Argon Adsorbed on Titanium Dioxide (Rutile). The data of Drain and Morrison have been analysed by several methods. Drain and Morrison assessed the heterogeneity of their sample from their enthalpy of adsorption data  

It is pertinent to mention that several authors have unjustifiably tried to evaluate the adsorption energy distributions directly from the relationship (103) but substituting isosteric enthalpies measured at normal adsorption temperatures (t 0). Koubek et have reiterated the difficulties in separating mutual lateral interaction energies from the effects of surface heterogeneity when analysing isosteric enthalpy data. 

In marked contrast to these results, Rudzinski and Jaroniec obtained a distribution function showing three distinct peaks. They used the Jovanovic 

Langmuir local behaviour -------, DR distribution corresponding to Jovanovic 

Rudzinski and Jaroniec explain the differences with the result of Dormant and Adamson and also Drain and Morrison in terms of the Jovanovic local isotherm. Since all the treatments ignore lateral interactions, the patchwise
